Except it's not necessarily what the original post wants. The OP wants the shebang "#!/usr/bin/env python3" to "work everywhere by default", for which I assume it's implied that it should work consistently everywhere. I'd prefer for the launcher's env search to also support versioned "pythonX[.Y][-32|-64]" commands such as "python3". I'd also prefer the env search to check the user and system "App Paths" key [1] if the name isn't found in PATH. Each subkey of "App Paths" is the name of a command such as "python3.exe", for which the fully-qualified executable filename is the key's default value. This is the Windows shell API equivalent of creating symlinks in "~/.local/bin" and "/usr/bin" on Unix systems. ShellExecuteExW checks "App Paths", but the launcher has to use CreateProcessW, which is beneath the shell API. > Would be great if it was consolidated, with one command "to rule them all." I'm in favor of "py" becoming the cross-platform command to run Python from the command line, since there's already a lot of inertia in that direction on Windows. Brett Cannon is working on a Unix version [2].
